What YouAt sends over SMS
YouAt sends exactly one type of SMS: a one-time 6-digit verification code, dispatched only when the end user actively taps "Continue" on the sign-in screen after entering their own phone number. No marketing, no promotions, no recurring alerts, no location updates, no third-party content.
Sample message (exact production text)
Your YouAt verification code is 123456. Reply STOP to opt out, HELP for help. Msg & data rates may apply.
How users opt in
Opt-in occurs inside the YouAt mobile app (iOS and Android). No third-party lists or purchased data are ever used.
- User downloads YouAt from the Apple App Store or Google Play Store.
- User taps "Get Started" on the onboarding screen.
- User is taken to the "What's your number?" screen (screenshot below).
- The screen displays the consent line directly beneath the heading: "We'll text you a code. Standard rates may apply."
- User enters their own mobile phone number and their name.
- User taps "Continue" to actively request an SMS verification code.
- Only after this explicit user action does YouAt send exactly one SMS to the number entered.
This flow satisfies the CTIA Messaging Principles & Best Practices standard for express written consent because the consent language is on the same screen as the input, the user must actively tap a button, and the message purpose is disclosed.

How users opt out
- Reply STOP to any YouAt message. Twilio's Advanced Opt-Out blocks all future messages to that number automatically.
- Delete their account in the app via Settings → Delete Account. The phone number is removed from our records within minutes.
- Uninstall the app. Since all SMS is user-initiated, uninstalling stops all future messages.
